Actually, the bridge in the Google Maps photo you link to is not a P&L bridge. That is the CSX bridge on their line to Owensboro. Here is the link showing both trestles mentioned in the article; the one on the left is the one getting replaced:

Ok, I found a better article. The bridge already entering replacement isn't listed on Bridgehunter, and doesn't appear to be in the NBI. It's a steel trestle about half a mile up the Salt River from this bridge. You can see a good view of it here;

There is a photo of the trestle at the bottom of the article, though not a very good one. They still want to replace the truss bridge also, but apparently don't have the money at this time. Sorry for panicking.

I'm still trying to get more information, but I'm afraid this bridge may be as good as lost. This article just came out today about closing the Bridges to the Past trail system, and I just happened to notice the mention of the replacement of a 1889 P&L Bridge. There is also mention of eventually replacing another bridge later on. This is the very first I've heard of any of this. I'm not sure this is the one, but it's the only bridge I can find that comes close to matching the article. I'll keep you posted with what I find out. Is anyone near this area that can get better info?
